NAS 4006 Compliance

High Purity AlumiPlate® Aluminum for NAS 4006 Fastener Systems

99.99% pure electroplated aluminum is an ideal coating for fasteners and fastener systems to meet NAS 4006 coating requirements. AlumiPlate Inc. can certify full compliance to this exacting standard.

NAS 4006 is the National Aerospace Standard that governs the application of aluminum coatings for fasteners, including titanium fasteners. This specification is commonly used for high strength steel, titanium, Inconel and Hastelloy aerospace fasteners that require corrosion resistance to environmental corrosion or to eliminate galvanic corrosion with dissimilar metals. The required coating thickness is 0.0002” – 0.0005”. Processing at temperatures higher than 400 °F is not allowed. As long as performance requirements are met, any coating process can be used (strike layers are allowed).
